This study examines the observed seasonal and annual rainfall trend and variability in Bhutan from 1996-2017. Using standard statistical methods, we utilized Mann-Kendall test and Sen's slope estimator to determine the trends in the seasonal rainfall of Bhutan. We analyzed the temporal variability and spatial pattern of rainfall by using the principal component analysis (PCA), Rainfall Anomaly Index (RAI), and Precipitation Concentration Index (PCI). Our results indicate that the summer season contributed to the 73% of the total rainfall in Bhutan while winter season contributed only 1%. Results from the PCI indicate that the rainfall distribution in the northeast part of the country is moderately concentrated while the south to the northwest portion experienced high fluctuation in rainfall distribution. PCA explains the 90.1% of the total variance is linked to the variability of Asian monsoon. The influences of ENSO/La Nina are possible causes for the variability of rainfall in Bhutan though this necessitates more investigations to corroborate.

In the Western North Pacific, there is little meteorological data available for the 19th century. We found historical documents at Chichi-jima in the Ogasawara (Bonin) Islands that report routine meteorological observations and weather conditions before 1906. In 1906, Japan Meteorological Agency began observations at Ohmura in the northwestern part of the island. The Home Ministry in Japan conducted the observations until 1906 at Ohgiura, the central part of Chichi-jima, which is 3 km away from Ohmura. We analyzed precipitation data at Ohgiura and Ohmura from 1975 to 2020 and found that the former is systematically greater than the latter. Therefore, we corrected pre-1906 precipitation at Ohgiura to ensure correlation with post-1906 precipitation at Ohmura. No discontinuous changes in the data were found around 1906. A previous study reported that annual precipitation at Ohmura for 1907-1944 was higher than that after World War II. We found that in some years from 1882 to 1906, the precipitation was less than that for 1907-1944, which agrees with the reported higher atmospheric pressure around Chichi-jima before 1906. Our study suggests that the trend of decreasing precipitation at Chichi-jima in the 20th century is not monotonous but a part of longer-scale temporal variations.

Illegal cannabis (Cannabis sativa L.) cultivation is still a social problem worldwide. Fifty inquiries on cannabis that Research Center for Medicinal Plant Resources (Tsukuba Division) received between January 1, 2000 and March 31, 2009 were itemized in to 8 categories; 1: seed identification, 2: plant identification, 3: indoor cultivation, 4: outdoor cultivation, 5: germination and growth characteristics, 6: expected amount of cannabis products derived from illegal cannabis plant, 7: non-narcotic cannabis and 8: usage of medicinal cannabis. Top three inquiries were 1: seed identification (16 cases), 3: indoor cultivation (10 cases) and 4: outdoor cultivation (6 cases). Characteristics of cannabis, namely seed morphology, germination and growth characteristics, and distinction from kenaf (Hibiscus cannabinus L.) that is frequently misjudged as cannabis, were studied to contribute for prevention of illegal cannabis cultivation.

A 24-yearold male was admitted to our hospital with his complaints of severe polydipsia, polyuria and headache. The total volume of urine reached up to nearly 15 liters per day. He showed nausea, vomiting, aggravation of headache and polydipsia by psychic stress during his hospitalization. No remarkable organic changes were observed in the laboratory data and other examinations. Being given a water deprivation test, he was diagnosed as psychogenic polydipsia. Psychological and environmental factors were considered to be related to the development of the disorder. He received supportive psychotherapy as well as drug treatment with no marked improvement. When the intake of water was restricted to the volume of 2 liters per day by using a scaled polyethylene vessel, the patient made a rapid recovery.

In this paper, we propose a method to generate various walking gait patterns for biped robots in real-time using an approximated dynamics model with two point masses representing motion of the feet and a linear inverted pendulum representing the horizontal motion of the torso. The motion of the inverted pendulum is calculated from the trajectories of the feet and the desired ZMP. Supposing these trajectories for the current gait and the next cyclic gait are given, the initial state of the inverted pendulum of the cyclic gait is calculated, and the desired ZMP trajectory of the current gait is modified so that the current gait converges to the cyclic gait using the concept called “the divergent component of the motion” as a relaxed boundary condition. Using these techniques, real-time gait generation is achieved which requires a comparatively small amount of modification of the desired ZMP trajectory while guaranteeing the continuity of the gait generation.

インホイールモータ型電気自動車のばね下重量増加に伴う乗り心地への影響を検証した。まず、車両を台上で加振した時の振動応答を実験により確認した。次に、科学計算ソフトである“MATLAB/Simulink”を用いて解析用車両を第一原理モデリングによってモデル化し、モデルベース開発手法による検討を行った。これらの結果より、ばね下重量の増加に伴い加振周波数の高い領域の乗り心地が良くなることが分かった。

Survival analysis is often used in studies of clinical epidemiology, but the existence of competing risks has not been adequately considered. Competing risks may hinder observation of the outcome of interest or modify the occurrence of the outcome. In the presence of competing risks, conventional survival analysis leads to biased results. To conduct a survival analysis in the presence of competing risks, researchers should select an appropriate method from the following two options: cause-specific hazard model and subdistribution hazard model. This article explains the issues raised by the presence of competing risks and describes methods to account for competing risks in survival analysis.

This study presents a possible large-scale factor of tropical cyclogenesis over the western North Pacific, which is triggered by Rossby wave breaking to the east of Japan. More than half of the wave breaking cases is accompanied by the tropical cyclogenesis. Results from a composite analysis for the wave breaking cases indicate that the genesis and development of tropical cyclones are dominant over the southwest quadrant of the wave breaking center, where an intrusion of the upper-level potential vorticity caused by the wave breaking and the consequent enhanced convection are seen. The number of tropical cyclones in the wave breaking cases exponentially increases in time during the developing stage of the wave breaking. The results of composite analysis further indicate that lower-level strong wind convergence and the associated enhanced convection, which are resulting from the wave breaking, is favorable conditions for the tropical cyclogenesis. An enhanced monsoon trough accompanied by the Pacific–Japan pattern resulting from the enhanced convection can regulate tracks of the tropical cyclones. These results show that the Rossby wave breaking can trigger the tropical cyclogenesis over the western North Pacific, through the southwestward intrusion of the upper-level potential vorticity and the consequent enhanced convection.

This study investigated the distributions of strong surface winds in the vicinity of Cape Erimo and the synoptic conditions favorable for inducing the strong winds by using scatterometer wind measurements and atmospheric reanalysis data. The wind around Cape Erimo is highly constrained by the topography, and the prevailing wind directions are split between westerly to west-northwesterly winds during the cool season and the easterly to northeasterly winds during the warm season. The zonal wind components in the region surrounding Cape Erimo are significantly correlated with the east–west sea level pressure gradient, which works as an index for the strong winds in the vicinity of Cape Erimo. Using composite analysis based on the index, the following atmospheric fields are presented. The low-pressure system passing over the Okhotsk Sea induces the northwesterly winds to the south of Cape Erimo during the cool season. The well-organized southwesterly winds are observed in the east of Cape Erimo when the southwesterly winds dominate during the warm season. The low-pressure system passing over Japan enhances the easterly winds around Cape Erimo during the cool season. The developed Okhotsk high induces strong winds to the southwest of Cape Erimo during the warm season.
